RHEL Engineering is moving the tracking of its product development work on RHEL 6 through RHEL 9 to Red Hat Jira (issues.redhat.com). If you're a Red Hat customer, please continue to file support cases via the Red Hat customer portal. If you're not, please head to the "RHEL project" in Red Hat Jira and file new tickets here. Individual Bugzilla bugs in the statuses "NEW", "ASSIGNED", and "POST" are being migrated throughout September 2023. Bugs of Red Hat partners with an assigned Engineering Partner Manager (EPM) are migrated in late September as per pre-agreed dates. Bugs against components "kernel", "kernel-rt", and "kpatch" are only migrated if still in "NEW" or "ASSIGNED". If you cannot log in to RH Jira, please consult article #7032570. That failing, please send an e-mail to the RH Jira admins at rh-issues@redhat.com to troubleshoot your issue as a user management inquiry. The email creates a ServiceNow ticket with Red Hat. Individual Bugzilla bugs that are migrated will be moved to status "CLOSED", resolution "MIGRATED", and set with "MigratedToJIRA" in "Keywords". The link to the successor Jira issue will be found under "Links", have a little "two-footprint" icon next to it, and direct you to the "RHEL project" in Red Hat Jira (issue links are of type "https://issues.redhat.com/browse/RHEL-XXXX", where "X" is a digit). This same link will be available in a blue banner at the top of the page informing you that that bug has been migrated.

Description Robin Hack 2019-07-15 11:18:53 UTC 
Description of problem:


Version-Release number of selected component (if applicable):
tuned-2.12.0-1.el8.noarch

How reproducible:
always

Steps to Reproduce:
1. echo 'isolated_cores=1-3' > /etc/tuned/realtime-virtual-guest-variables.conf
2. tuned-adm profile realtime-virtual-guest
3. tuned-adm verify --ignore-missing

Actual results:
After cmd on output:
Verification failed, current system settings differ from the preset profile.
You can mostly fix this by restarting the Tuned daemon, e.g.:
  systemctl restart tuned
or
  service tuned restart
Sometimes (if some plugins like bootloader are used) a reboot may be required.
See tuned log file ('/var/log/tuned/tuned.log') for details.

In logs:
2019-07-15 06:54:01,916 ERROR    tuned.plugins.plugin_scheduler: verify: failed: 'SMP affinity of IRQ 0' = '[0, 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20, 21, 22, 23]', expected '[0, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20, 21, 22, 23]'

Expected results:
dunno.. better no error message in log, because it's breaks my tests

Comment 3 Ondřej Lysoněk 2019-07-15 11:25:17 UTC 
Thanks for the report. I believe the problem is that the affinity of certain IRQs cannot be changed. We should probably agregate these kind of issues and produce only a single warning message for all those IRQs.

Yes, it seems it's the case:
